Refactor Neon implementations of SAD functions

Use a Neon vector accumulator and only perform a reduction once at
the end of the function rather than on every loop iteration in
sad<w>xh_neon() helper functions.

Implement aom_sad<w>x<w>_neon() functions using the sad<w>xh_neon()
helpers to reduce code duplication.
